FLOCR COVERING AND PROCESS OF MAKING Application filed January 10, 1922, Serial m5. 528,298. Renewed Septeniber 1, 1925.

\Be it known that I, CALEB MARSHALL TAYLOR, a citizen of the United States, rcsiding at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Floor Coverings and Processes of Making Same, of which the following is a specification.

This invention relates to floor coverings and to a process of making the same.

The floor covering provided is of that type known as felt base floor coverings and particularly such materials in which an asphalt or bitumen impregnated base is used.

The invention is also peculiarly adapted for use in combination with all floor coverings in which either the wear surface or the opposite face is formed of paint or other material containing linseed oil or other oil, or any material subject to saponification, or

V removable under the action of soap and the usual floor cleaning materials.

Bitumen impregnated felt base floor coverings may be recognized by the main dark body which is particularly evident when the material is cut. The felt of such bases may be made from rags, or from paper or any cellulose material, or from a mixture of such materials,v thoroughly impregnated with asphalt or tar or some suitable bituminous material. When used as a supporting base for floor covering it isthe usual-practice to coat the bitumen impregnated base with a layer of paint which is known as the sealing coat and often to apply various painted designs, all'of Whichmay be applied in any convenient manner. Also, a coat of paint is applied to the opposite or under surface of the impregnated base to cover the gark and unsightly bitumen impregnated ase. s For. the manufacture of such bitumen impregnated bases it has been found that the wear paint and the decorative paint may become discolored due in part to the inherent nature of the bitumen of the base. Also in drying the paint coats itis necessary to dry at relatively low temperatures and for a longer period of time, often as long as four or five days. A higher temperature and more rapid drying would tend to liquefy the bitumen and delay proper drying of the paint and also discolors the paint due to the release of materials from the base. Thus a baking temperature of 175 F. or more,

1 such as is desirable for treating to a ba the paintcoats, is not advisable in the usual dryingof such coated bases.

After the present known product is completed it is usually necessary to place paper between adj acent'surfaces when the material is rolled or stacked in layers to prevent the adjacent painted surfaces from adhering.

It is well known that all such painted surfaces, and also that the surface of the materialknown aslinoleum, are worn away. by the use of soap and water because of "saponification by .such cleaning materials onthe Oils in the paint and linoleum.

provides a.coating. .of a non-saponifiable materlal on 'one or The present 1 lnvention both faces of the bitumen impregnated floor covering base. If the sides or marginal edges are also covered, the covering constitutes a sealing coatin peculiarly adapted for use on rug sizes of oorcoverings. Thus the relatively inexpensive bitumen impregnated base may be used, the desirable features retained, and most of theundesirable characteristics eliminated. The paint coats applied over the sealing, coat do not become iscolored by the material within the bitumen impregnated felt even when subjected 111g temperature, and thetime required for drying the paint coats is reduced to a much shorter length of time than heretofore possible where similar impregnated bases are used.

In producing the floor covering of this invention, the usual asphalt or bitumen impregnated felt base is used. A solution is prepared of a mixture of nitrocellulose and a solvent tjherefor; quantity 0 a semi-drying or drying vegetable oil is added to the mixture as a softenmg medium. It is desirable to add a quantity of resin. The solution is applied to one or both sides of the impregnated base as a sealing coat by any well known coating process. The solution thus applied is quickly dried on the base at a suitable drying temperature of approximately 140 "F. The impregnated base is thus provided with an impervious; film which may be used wher ever an ordinary bitumen impregnated base would before not have been acceptable on account of the sticky tarry nature of its ma terials. The coated base may be used as" such for afloor covering. or preferably may be further coated with wear and decorative Preferably the desired 1 paint coats, or the sealing pyroxylin coat One satisfactory mixture for the coating solution may be made by using 12 parts by weight of nitro cotton, and 8% parts by weight of a; solvent mixture which may be composed of 35per cent-of acetone 011 and .65 per cent of sucha diluent as solvent naphtha, xylol, toluol, or benzol. Any vwell known working formula may be used for combining such a mixture of drying or semidrying vegetable oil and nitl'o cotton. To

such a mixture 12 parts by weight of linseed oil or other semi-drying or drying vegetable oil can be added. 12 parts of a resin, such as cuinaron, may be added to advantage.
